Dennis Sullivan

May 12, 1956 — December 10, 2020

Dennis P. Sullivan

Age 64, unexpectedly, went to be with Our Lord on December 10, 2020.  He is survived by his mother, Ann Sullivan, brother Terry Sullivan, and sister Beverly Kantz (Edward), niece and Goddaughter Samantha Kantz, nephew and kindred spirit Shaun Kantz, and so many wonderful friends who will miss him dearly.

He was preceded in death by his father Patrick William Sullivan.

For 40 years Dennis was a dedicated IT specialist for the National Center for Juvenile Justice.  Working with Judge Cohill and Hunter Hearst II, Dennis impacted generations of young people as their advocate in the juvenile justice system.

For countless years Dennis was a devoted caregiver to his mother.

Always a kind, generous, and genuine person, he spent much of his time and talent giving to others.  He volunteered for many years at the former St. Francis de Sales Church and the Martina Spiritual Renewal Center, as well as singing with the Duquesne University Chapel Choir. 

Christmas was his favorite time of year and fittingly he will be remembered with a Christmas celebration. Visitation will be 2-4 & 6-8 PM SUNDAY at the McDermott Funeral Home, Inc., 1225 Chartiers Avenue, McKees Rocks.  Due to current Covid-19 regulations,  there will be a continuous rotation of (10) visitors into the funeral home at one time.  Mass of Christian burial will be on Monday, December 14th, 2020 9:30 AM at the St. Mary’s worship site of Archangel Gabriel Parish in McKees Rocks. Masks and social distancing are required at the church for the health and safety of all visitors.  Following Dennis’s example of true generosity, in lieu of flowers, a donation can be made to the Martina Spiritual Renewal Center.
